PIN-FASTENING.

SPECIFICATION forming part of Letters Patent No. 485,005, dated October25, 1892.

Application filed March 11, 1892. Serial No. 424,491. (No model.)Patented in Germany April 23, 1891, No. 59,146. and in Belgium April25,1891,N0-94=,667-

T0 at whom it may concern.-

Be it known that I, THEODOR FAHRNER, a citizen of the Grand Dukedom ofBaden, residing at Pforzheim, in Baden, and Empire of Germany, haveinvented certain new and useful Improvements in Pin-Fastenings, (forwhich I have obtained a patent in Germany, No. 59,146, dated April 23,1891, and in Belgium,No.94,667,dated April25,189l,)of which thefollowing is a specification.

This invention relates to a pin-fastening which is applicable generallyto pins used in jewelery, such as scarf-pins,loutis also applicable topins used for other purposes.

It consists in the various features of improvement more fully pointedoutin the claim.

In the accompanying drawings, Figures 1 and 2 are rear and frontelevations of a pin provided With myimprovement. Fig. 3 showscorresponding views of a modification.

The letter A represents a pin provided with a downwardly-curved guard B,made either in one piece with the pin, as in Figs. 1 and 2, or in aseparate piece therefrom, as in Fig. 3. The guard B is so curved that itcrosses the shank of the pin twice, so as to form an upper closed loopand a lower open loop. In

Figs. 1 and 2 the first crossing is effected by the intertwisted portion0, while the lower crossing is effected by the spiral tipD of the guard.In Fig. 3 the upper crossing is single and takes place at the point C.

In use the pin is pushed into the scarf or other material up to thepoint C or C, with the spiral D lying in front of the pin-shank. Afterthe pin is seated it is revolved through a semi-revolution, so that thespiral comes to lie back of the pin-shank, as shown in Fig. 2 and theright-hand side of Fig.3. This will iuterpose the spiral betweenpin-shank and the punctured part of the scarf and will effectivelyprevent the pin from being withdrawn. It will be necessary to turn thepin back into its original position before it can be removed. It will beseen that by crossing the pin and guard at the upper point the scarf cannever slip up above such point and the head of the pin will thereforealways remain properly exposed. Of course the guard B may be curvedeither to the right or left of the pin-shank, as may be desired.

What I claim is- A pin provided with a downwardly-curved guard thatcrosses the pin-shank twice to form an upper closed loop and a loweropen loop, substantially as specified.

Signed at Stuttgart, \Viirtemberg, this 23d day of February, 1892.
